Sleep entails significant changes in cerebral hemodynamics and metabolism. Yet, the way these processes evolve throughout wakefulness and sleep and their spatiotemporal dependence remain largely unknown. Here, by integrating a novel functional PET technique with simultaneous EEG-fMRI, we reveal a tightly coupled temporal progression of global hemodynamics and metabolism during the descent into NREM sleep, with large hemodynamic fluctuations emerging as global glucose metabolism declines, both of which track EEG arousal dynamics.

RCI, NHSBT, Filton, UK.
Introduction: Introduction The Hy antigen is one of ten red cell antigens belonging to the Dombrock blood group system, with an antigen frequency of almost 100% in the majority of populations. Alloantibodies to high prevalence antigens cause difficulties with antibody identification and exclusion in serological investigations.
Case Presentation: This review describes the management of four antenatal cases where the presence of alloanti-Hy had been identified.

There is currently no cure or disease-modifying treatment for post-traumatic osteoarthritis (PTOA). This study aims to assess the efficacy of dimethyl fumarate (DMF), a US-FDA approved drug for multiple sclerosis, as a treatment for PTOA. PTOA was induced in male Lewis rats by medial meniscal transection (MMT) surgery, and DMF was intra-articularly administered once, one week following surgery.

Biomedical Sciences College & Shandong Medicinal Biotechnology Centre, Shandong First Medical University & Shandong Academy of Medical Sciences, Jinan, China.
Objective: This study aimed to investigate the effect of angelicin on the NSCLC tumor growth.
Background: Accumulating evidence shows that cancer-associated fibroblasts (CAFs) play an important role in tumor progression and metastasis, making CAFs an increasingly attractive target for therapeutic intervention. Targeted therapies against CAFs have been considered to have the potential to significantly improve cancer treatment outcomes, overcome resistance, and improve immune evasion.
Mechanisms of Antitumor Activity of Low Doses of Radiation Associated with Activation of Cells' Defense System.

State Research Center-Burnasyan Federal Medical Biophysical Center of Federal Medical Biological Agency, 123098, Moscow, Russia.
Background: The effects of ionizing radiation (IR) involve a highly orchestrated series of events in cells, including DNA damage and repair, cell death, and changes in the level of proliferation associated with the stage of the cell cycle. A large number of existing studies in literature have examined the activity of genes and their regulators in mammalian cells in response to high doses of ionizing radiation. Although there are many studies, the research in effect of low doses of ionizing radiation remains limited.
